This case report describes a 66-year-old woman with dyspnea and hemoptysis, whose imaging confirmed diffuse alveolar hemorrhage and whose echocardiography showed acute severe mitral regurgitation. The patient underwent transcatheter edge-to-edge repair (TEER) using the Pascal device after initial preference over surgery. Recurrent mitral regurgitation and persistent pulmonary hemorrhage led to clinical deterioration and death despite intensive management and supportive care.",{"@graph":14,"@context":73},[15,34,56],{"@type":16,"itemListElement":17},"BreadcrumbList",[18,23,27,31],{"item":19,"name":20,"@type":21,"position":22},"https://docshare.wps.com","Home","ListItem",1,{"item":24,"name":25,"@type":21,"position":26},"https://docshare.wps.com/document/","Document",2,{"item":28,"name":29,"@type":21,"position":30},"https://docshare.wps.com/document/healthcare/","Healthcare",3,{"item":32,"name":10,"@type":21,"position":33},"https://docshare.wps.com/document/transcatheter-edge-to-edge-repair-for-severe-acute-mitral-valve-regurgitation-in-diffuse-alveolar-hemorrhage-case-report/435811/",4,{"url":32,"name":10,"@type":35,"image":36,"author":41,"headline":10,"publisher":44,"fileFormat":47,"inLanguage":8,"description":12,"dateModified":48,"datePublished":49,"encodingFormat":47,"isAccessibleForFree":50,"interactionStatistic":51},"DigitalDocument",{"url":37,"@type":38,"width":39,"height":40},"https://docshare.wps.com/thumbnails/transcatheter-edge-to-edge-repair-for-severe-acute-mitral-valve-regurgitation-in-diffuse-alveolar-hemorrhage-case-report/435811.png","ImageObject",300,407,{"name":42,"@type":43},"moss~","Person",{"url":19,"name":45,"@type":46},"DocShare","Organization","application/pdf","2026-10-29","2026-09-29",true,{"@type":52,"interactionType":53,"userInteractionCount":55},"InteractionCounter",{"@type":54},"ViewAction",9,{"@type":57,"mainEntity":58},"FAQPage",[59,65,69],{"name":60,"@type":61,"acceptedAnswer":62},"What condition was identified as the final diagnosis in this case?","Question",{"text":63,"@type":64},"Diffuse alveolar hemorrhage was established as the final diagnosis after bronchoscopy confirmed intra-alveolar bleeding.","Answer",{"name":66,"@type":61,"acceptedAnswer":67},"Why did management become especially complex after TEER?",{"text":68,"@type":64},"The patient required anticoagulation for new-onset atrial fibrillation, while TEER did not prevent recurrent mitral regurgitation and worsening diffuse alveolar hemorrhage.",{"name":70,"@type":61,"acceptedAnswer":71},"What treatment did the patient choose instead of surgical valve replacement?",{"text":72,"@type":64},"The patient chose transcatheter edge-to-edge repair (TEER) for acute severe mitral regurgitation.","https://schema.org",{"og:url":32,"og:type":75,"og:title":10,"og:site_name":45,"og:description":12},"article",{"robots":77,"canonical":32},"index,follow",{"doc_id":79,"site_id":7},435811,1790716224,{"code":4,"msg":82,"data":83},"success",[84,88,92,96,101,106,110,115,119,122,126],{"id":22,"doc_module":4,"doc_module_name":25,"category_name":85,"show_sort_weight":86,"slug":87},"Story & Novel",90,"story-novel",{"id":26,"doc_module":4,"doc_module_name":25,"category_name":89,"show_sort_weight":90,"slug":91},"Literature",80,"literature",{"id":33,"doc_module":4,"doc_module_name":25,"category_name":93,"show_sort_weight":94,"slug":95},"Exam",70,"exam",{"id":97,"doc_module":4,"doc_module_name":25,"category_name":98,"show_sort_weight":99,"slug":100},5,"Comic",60,"comic",{"id":102,"doc_module":4,"doc_module_name":25,"category_name":103,"show_sort_weight":104,"slug":105},6,"Technology",50,"technology",{"id":107,"doc_module":4,"doc_module_name":25,"category_name":29,"show_sort_weight":108,"slug":109},7,40,"healthcare",{"id":111,"doc_module":4,"doc_module_name":25,"category_name":112,"show_sort_weight":113,"slug":114},8,"Research & Report",30,"research-report",{"id":55,"doc_module":4,"doc_module_name":25,"category_name":116,"show_sort_weight":117,"slug":118},"Religion & Spirituality",20,"religion-spirituality",{"id":117,"doc_module":4,"doc_module_name":25,"category_name":120,"show_sort_weight":117,"slug":121},"World Cup","world-cup",{"id":123,"doc_module":4,"doc_module_name":25,"category_name":124,"show_sort_weight":123,"slug":125},10,"Lifestyle","lifestyle",{"id":127,"doc_module":4,"doc_module_name":25,"category_name":128,"show_sort_weight":97,"slug":129},19,"General","general",{"code":4,"msg":82,"data":131},{"doc_id":79,"user_id":132,"nickname":42,"user_avatar":133,"doc_module":4,"category_id":107,"category_name":29,"doc_title":10,"doc_description":12,"doc_content":134,"file_id":135,"file_url":136,"file_type":137,"file_size":138,"view_count":55,"is_deleted":4,"is_public":22,"is_downloadable":22,"audit_status":22,"page_count":107,"language":139,"language_code":8,"site_id":7,"html_lang":8,"table_of_contents":140,"faqs":141,"seo_title":142,"seo_description":12,"update_tm":143,"read_time":144,"preview_page_count":4},962090895452,"https://ap-avatar.wpscdn.com/davatar_a8503ba1806abce46bf441b54a3ca4cd","e-ISSN 1941-5923  \n© Am J Case Rep, 2025;

Emerging evidence of transcatheter edge-to-edge repair (TEER) use for treating acute mitral regurgitation has promoted TEER as a promising alternative to mitral valve surgery, owing to reduced mortality and complications.  \nCase Report: A 66-year-old female patient with a history of thyroid nodules presented with dyspnea and hemoptysis. Imaging confirmed bilateral pleural effusions, with opacities suggestive of diffuse alveolar hemorrhage, and echocardiography revealed acute severe mitral valve regurgitation. The patient chose TEER over surgical valve replacement. After discharge on apixaban for new-onset atrial fibrillation, she returned a week later with melena and worsening dyspnea. Echocardiography demonstrated recurrent mitral valve regurgitation, and bronchoscopy confirmed diffuse alveolar hemorrhage. Despite aggressive management, the patient died.  \nConclusions: This case highlights the complexity of managing acute severe mitral regurgitation complicated by diffuse alveolar hemorrhage in a patient requiring anticoagulation. Although a TEER procedure using the Pascal device was performed, the patient’s condition continued to deteriorate, underscoring the importance of individualized treatment strategies, as surgical mitral valve replacement may offer more definitive hemodynamic correction in selected cases.  \nKeywords: Cardiovascular Diseases • Dyspnea • Hemorrhage  \nFull-text PDF: [https://www.amjcaserep.com/abstract/index/idArt/949953](https://www.amjcaserep.com/abstract/index/idArt/949953)  \n2607  —  4  14  \nPublisher’s note: All claims expressed in this article are solely those of the authors and do not necessarily represent those of their affiliated organizations, or those of the publisher, the editors and the reviewers.
